Toall whom it may concern:

Be it known that I,'EDWIN G; WILLIAMS, citizen ofthe United States,residing at Oarney, in the count of Lincoln and State of Oklahoma, havemvented certain new and useful Improvements in Cotton-Choppers, of whichthe followin is a specification.

This invention re ates to farm implements,

and more particularlyv to cotton choppers,

and has for its object to provide a chopper which will be arranged forad'iistment to suit different conditions, and w ich will include a noveland convenient arrangement ther objects and advantages will be apparentfrom the following description and it cific structure shown anddescribed ma will be understood that changes in the spe be made withinthescope of the claims wit out de arting from the spirit of theinvention.

n the drawingsformin a portion of this specification, an

in whic like numerals of reference indicate similar parts in the severalviews, Figure 1 is a side elevation of the present invention; Fig.2 isa' top plan; Fig. 3 is a detail perspective-view Fig. 4 is a detail sec--tion through the box for one ofthe forward.

disks; Fig; 5 is a 'detail section through the box for one of thenotched disks Fig. 6 is a detail section of a modified form of the diskad'usting means. i

eferringnow to the drawings, the present invention includesa-longitudinal, horizontally extending draft bar 10, having its forwardportion turned upwardly as shown at 1]. andprovided with a longitudinalseries of perforations 12 in order that a clevis 13 may e adjustedverticall thereon; i At 1ts rearward en the draft bar 10 is secured to apair of rearwardly divergent members 14 having guiding handles 15secured thereto at their rearward portions. The draft bar has itsrearward end secured between the forward ends of the beams 14, and

disposed against the under faces of the beams at their forwardextremities, there is a transversel extending plate 15. Bolts 16 arepasse through the end portions of the plate 15 and through the members14 and these bolts have circular radially notched plates 17 engagedtherewith beneath the plate 15 and with their notched faces directeddownwardly. The plates 17 carr rearward extensions 18 rovided wittransversely spaced depending ears 19 in which are pivoted the forwardends of rearwardly extending arms 20, which are thus arranged forvertical pivotal movement.

shown, and has a central 0 ening 23 in which the lower portion of eacholt 16 is engaged A half-box 21 has a radially notched upper face 22,as.

for cooperation of the notched faces of the half-box and plate 17 tohold the half-box at different points of its pivotal movement with thebolt 16, the latter having a. head 16 seated in a recess24. formed inthe inner face of the half-box; A nut 16 is engaged with and through thestructure just described, the

disks are adjustable-to suitdifferent conditions. 1 Y

The rearward ends of the arms 20 carry members 29 havingradially notchedcircular rearward faces 30 and having openings 31 7 formed therethroughat their 'forward por tions. A bolt 32 is engagedthrough the rear wardportion of each member 39 and extends rearwardlv from the center, of'the notched face 30. Engaged with this bolt 31, there is a half-boxing83 similar to the half-boxing 22, and having a notchedface 33' for 00-operation with the face .30. This half-boxing '33 carries a half-boxing34. A bearing is thus formed at the rearward end of each arm 20 forthenreception respectively of stub shafts 35, these shafts extending at,their inner ortions through the centers of cho 4 pin isks 36. Inwardlyof the disks, t e stu shafts carry the members 37'and 38 of a knucklewhich thus connects the two disks 1 for simultaneous rotation and itwill be observed that the mounting 'of' the bearings is such that thedisks may be adjusted to vary their angle. 1 By reason of the rearwarddivergence of the arms 20, the disks are-brought together at their lowerforward portions, and the disks are provided .withperipheral notches39,as

shown. The-connection of the disks is such that the notches thereof arebrought into registration, and the arrangement is thus 1 ally to aslight extent to engage the guide.

such thatthe cotton plants remain uncut at the oints at which theregistration of the notches occurs. I a

Anupwardly extending arch 40 is secured to the rearward portions of themembers 14 and tothe handles 15, the arch thus acting is pivoted betweenthe lower endsof thedownwardl wardly of t e pivot point, the levercarriesa guide 45, through which isengaged an upwardly extendingnotchedrod 46 which is bifurcated at its lowerend and has its resultant spacedortions 47 secured to the members 41 of t e arch. As .willbe readilyunderstood, the lever may be moved later with the notches of the rod46andrthu's hold the lever at different'points of its pivotal movement. 7The forward end of the lever 44 is connected by means of a chain 48 witha yoke 49- secured at the lower ends of its legs to thecrearwardportions of the arms 20 and itwill thus be seen that operation of thelever results in vertical movement of the arms 20 andtherewith the.disks 36.

In Fig. 6, there is shown a form of the invention in which the guide451and member 46.;

areomitted, a notched rod A being secured to the yoke 49 and passedthrough an opening 50 forniedin a plate 51 secured between the upperportions of the downwardly turned portions 43 of the members 41. Thisrod A 1s movable for engagement of its notches The arch consists" ofturned portions 43 and rear-v with the edge of the opening 50, and thusthe disks may be held at different points of their vertical movement. As ring 52 is arranged to hold the rod A yieldab y in position to engageits notches with the plate 51. 4

1: Will be readily understood, the forward disks 28 excavate the earthfrom the cotton plantswhich are then chopped by. thedisks 36.. Suitablesupports are providedv for the implement, whic, are disclosed asrunnersB in the drawings. 1 1

What is claimed is;

able excavating disks, of vertically adjustable chopping disks, saidchopping disksbe- 1. In an implementof theclass described, thecombination with horizontally adjust+ ing mounted for rotation indiagonal planes rearwardly of the excavating disks, the chopping diskshaving registering peripheral notches, connections between theexcavating and chopping disks,and means for moving the chopping disks ina vertical plane.

2. an implement of the class described,

the combinatlon with frame members, of

disks arranged for vertical. movement with respect to the frame members,an upwardly extending arch secured to the frame members and having theirspaced members at the 'upper ends turned inwardly and then downwardly, alever pivoted between the downwardly turned ends, and connectionsbetween the lever and disks for simultaneous movement thereof.
